The whole face mask situation to me is straightforward. If they advise using a tissue to cover your nose and mouth when you sneeze or cough then surely a face mask is more effective than that. Also it restricts droplets being emitted when people speak. The only reason they didn't push it is there was a shortage. Even now I haven't seen any for sale anywhere. That suggest there isn't any as retailers would otherwise have shelves full of them to make a profit.
I was gobsmacked this morning to hear our approach to just allowing thousands of people into the country because the virus was already here so it didn't make a difference. Incredible.
